The Chunochi, Dhamman, Sounchal, Sarsawah and Malhar areas lie along the eastern limb of Hazara-Kashmir Syntaxis. This is an active fold-and-thrust belt in the sub Himalayas of Pakistan. The Early Miocene to Recent sedimentary rock sequence is exposed in the area. The stratigraphic sequence of the study area includes the Early Miocene Murree formation, Early to Middle Miocene Kamlial formation, Middle to Late Miocene Chinji formation, Late Miocene Nagri formation, Late Miocene Dhok Pathan formation, Pliocene Soan formation and Pliestocene Mirpur formation. The Baluch syncline, Panakah anticline and Nainsukh anticline are the major folds. These are open to isoclinal in nature. The Dhamman fault, Tangai fault, Riasi fault, Gali Samiar fault, Godri Badshah- Kotli fault, Chak Nasru fault, Nuhi Sarota fault and Hill Kalan fault are the major faults. The Riasi fault, Godri Badshah-Kotli fault and Chak Nasru fault are active faults. The sedimentary structures observed in the area are cross bedding, load cast and rip ups. The facing of the stratigraphic units is marked on the basis of these structures.
